The answer is 27
To find the length of a triangle or what ever shape your trying to find all you have to do is multiply width times the area. * * * * * Or, if you want the correct answer, you could try to divide the area by the width. That assumes the shape is a rectangle and that the area and width are known!
my idea is that to find the area of a 2 dimensional figure you have to multiply length *width which equal the area except a triangle and some other figure
You first multiply the length and the width, the you divide it by 2.
If Length * Width = Area, then Area ÷ width = Length
Rectangle: length x width triangle: (base x height)/2
To get the area of a triangle you multiply length by width and divide by two.
Area = (length) times (width)Length = (area) divided by (width)Width = (area) divided by (length)
The area of a right angled triangle would be .5 * length *width where the length is the height of the triangle. To find the height of the triangle, take the sine of 45 degrees, which is the degree of the angles other than the 90 degrees, and multiply it by the length of one of the two equal sides. The width of the triangle is the length of the bottom side.
For a rectangle, area equals length times width. To find the length given the width and area, divide the area by the width.
To find the relationship in width and area you can use the formula area/length = width. To find the area of a room you multiple the length by the width.
The area of triangle is : 60.0
Width * Length = Area so..... Width = Area / Length
